Problem 2 - Abnormal Psychology: An Integrative Approach

Question

Check your understanding of eating disorders by identifying the proper disorder in the following scenarios: (a) bulimia nervosa, (b) anorexia nervosa, and (c) binge-eating disorder. I noticed Elena eating a whole pie, a cake, and two bags of potato chips the other day when she didn't know I was there. She ran to the bathroom when she was finished and it sounded like she was vomiting. This disorder can lead to an electrolyte imbalance, resulting in serious medical problems. _____________.

Step-by-Step Solution

Answer

Bulimia nervosa.

Step 1: Understand the Symptoms

First, identify the symptoms described in the scenario: Elena is eating large quantities of food rapidly. After eating, she goes to the bathroom to vomit. This behavior suggests a cycle of binge eating followed by purging.

Step 2: Identify the Disorder

Match the symptoms to the correct eating disorder. Bulimia nervosa is characterized by binge eating followed by actions to prevent weight gain, such as vomiting, and can lead to electrolyte imbalances due to purging.

Step 3: Confirm the Symptoms

Ensure the symptoms match bulimia nervosa: binge eating, followed by purging (vomiting), and risk of electrolyte imbalance are consistent with bulimia nervosa, confirming this diagnosis.

Key Concepts

Bulimia Nervosa

Bulimia Nervosa is an eating disorder characterized by cycles of binge eating followed by compensatory behaviors, such as purging, to prevent weight gain. It involves consuming a large amount of food in a short period, often accompanied by feelings of loss of control. Afterward, individuals might vomit, use laxatives or diuretics, or engage in excessive exercise.
Bulimia can be very harmful to the body. The repeated cycle of bingeing and purging takes a toll on physical health, including:

• Electrolyte imbalance, which can cause heart problems.
• Inflammation of the esophagus.
• Tooth decay from stomach acid during vomiting.

It's crucial to seek help if you or someone you know is showing symptoms of bulimia nervosa. Mental health professionals can provide the support and treatment necessary to manage and recover from this disorder.

Anorexia Nervosa

Anorexia Nervosa is another serious eating disorder that primarily affects young women, though anyone can develop it. Those with anorexia often have an intense fear of gaining weight and a distorted body image. They typically restrict their food intake and might become dangerously underweight.
The consequences of anorexia nervosa are severe and can include:

• Bone thinning (osteoporosis).
• Anemia and muscle wasting.
• Low blood pressure, slowed breathing and pulse.
• Severe malnutrition.

Understanding anorexia nervosa is important because of its potential to cause life-threatening health issues.
Detection and early treatment improve recovery outcomes significantly, involving cognitive-behavioral therapy and sometimes medical intervention to restore weight healthily.

Binge-Eating Disorder

Binge-Eating Disorder (BED) is characterized by recurrent episodes of eating large quantities of food often quickly and to the point of discomfort. Unlike bulimia nervosa, binge-eating episodes aren’t followed by purging behaviors. People with BED might feel a lack of control during binges and experience feelings of shame or guilt afterward.
BED is the most common eating disorder in the United States and can lead to several physical health issues, such as:

• Obesity and related health problems, like Type 2 diabetes and cardiovascular disease.
• High blood pressure.
• Sleep apnea.

Recognizing and treating BED early can prevent further health complications. Successful treatment strategies include psychological counseling, medication, and support groups that focus on healthy eating habits and emotional coping skills.
